In winemaking, the sugars in grapes undergo fermentationby yeast to yield CH3CH2

Question

In winemaking, the sugars in grapes undergo fermentationby yeast to yield CH3CH2OH and CO2. During cellularrespiration, sugar and enthanol are "burned" to water vapor andCO2. A) Using C6H12O6 for sugar, calculate ÄH of fermentation and of respiration(combustion). B) Write a combustion reaction for ethanol. Which has ahigher ÄH for combustion per mole of C, sugaror ethanol? -69....correct -2538.7...correct ethanol..correct

I just need help with b)....balancing the combustion rate equation...please include physical states!!!!! thank you. HINT:.

Start by writing a balanced chemical equation for the fermentation reaction of C6H12O6 and for the respiration reaction (combustion) of C6H12O6...what formula should be used to find the standard enthalpy of a reaction? Use the standard enthalpy of formation values from your textbook when calculating the standard enthalpy of reaction for both fermentation and respiration

Explanation / Answer

C2H5OH(liq)+ 3O2(g) --> 2CO2(g) +3H2O(liq)

Also you can write

2C2H5OH+ 7O2 --> 4CO2 +6H2O
